Why does my period stop while I'm sleeping and bathing? Is that normal? Or am I just imagining things?

If you’re sleeping (that is lying down, not asleep at your desk in French class), the blood and tissue will build up inside you. So if you’ve been snoozing for eight hours and then hop out of bed, it might take a bit for your period to start flowing down again.

As for bathing, your period doesn’t actually stop flowing in water. “For most young women, there isn’t much flow to the outside when you’re in water,” says Dr. Paula Hillard, director of women’s health at the University of Cincinnati College of Medicine. However, even if you usually don’t bleed in water, don’t skip the tampon. It’s better to be safe than sorry.
